STREET-WASHER.

SPECIFICATION forming part of Letters Patent No. 364,737, dated June 14,1887.

Application filed March 21, 1887. Serial No. 231,163. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM STRONG, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of 5'Indiana, have invented certain new and useful Improvements in Street-Washers, of which the following is a specification.

My invention relates to stationary streetwashers, such as are commonlyused on streets to and private grounds to bring the water from awaterworks pipe located in the ground up to the surface, and supply thesame to a portable sprinkler hose or pipe; and the objects of myimprovements are to provide a street-washer 1 5 the outlet or dischargeof which is constructed in such a manner that the sprinkling-hose can becarried around horizontally without becoming twisted or kinked at thepoint of connection, while at the same time a perfect water-tight jointis obtained. Heretofore to obtain these objects separate hose couplingswere used, some of which were in form of a swivel, and others in shapeof aball-and-socket A joint. All had to' be attached to the supplypipein the street-washer box and to the end ot" the sprinkler-hose',beingdistinct couplings, and forming a connecting-link between thestreet-washer and the hose. These couplings when left on thesupply-pipe, rising above the level of the ground, prevented the closingof the lid of the box, thus causing accidents and breakages, or whentaken off each time after ushig the sprinkler they created considerabletrouble and labor. Further, the cost of these 3 5 separate and completecouplings was not the least obstacle to their general use. I avoid theseobjections by making the end of the streetwasher part of thecoupling, asshown in the accompanying drawings, in which- 0 Figure 1 is a verticalcrosssection through an ordinary street-washer box with my improvementswhen the watersupply is shut off from the street-washer, and Fig. 2 asimilar section with the water turned on and the hose attached.

Similar letters refer to similar parts th roughout'the several views.

A is the vertical cast-iron casing, in which the water-pipe B rises fromthe horizontal wator-main in the ground.

The pipe B connects into the street-washer cap or socket D, which,forming the continuation of the pipe B, terminates in the'cast-iron box0, secured to the casing A on alevel with the surface of theground. I

In a screw-threaded shoulder, d, on the cap.

D operates a lifting-screw, S, which extends up into the box 0, and issecured and constructed in such a manner that the turning of the key Konthe head of the screw S raises or lowers the cap D and the pipe 13,connected therewith, which raising or lowering opens or shuts a valvelocated at the connection of the pipe 13 and the water-works main, thusturning the water on or shutting it off from the 6 street-washer cap orsocket D.

The device described so far is old and the construction nearly the samein all the streetwashers in use at present.

To add my improvements I do not make any changes. The same box, cap, andmethod of turning thewater on and off are used; only, instead of havingthe end of the pipe D screw threaded on the outside, which is necessarywhere the hose is secured directly to the pipe, 7 5 or where a separatecoupling is employed, I cut the screwthread on the inside, as shown inthe drawings. I then insert into the pipe orsocket D apipe, E, ofsmaller outer diameter than the inner diameter of the pipe D, andprovided at its lower end with a flange, e, and branching off at itsupper end into a horizontal direction to connect with thesprinkling-hose II. Awasher, g, is slipped over the pipe E. Somewater-tight elastic packing, P, is then stuffed into the space betweenthe pipes E and D onto the washer g, and, finally, a collar, F, isscrewed down into the socket D, closely fitting around the pipe E. Toallow the packing Pto be stuffed firmly 9 and tightly in its placearound the pipe E and onto the washer 9, so that it will form aperfectly water-tight joint, even if the pressure of the water turned onis small, the socket D is provided with an inner projecting shoulder,m,- or the chamber in the socket may be of a smaller diameter down fromsuch apoint that the washer y can only go down into the socket thedistance required for a sufficient amount of packing and the collar F,and not more, forming a solid foundation to pack on.

When the water is turned on by raising the supply-pipe B from its valveon the waterworks inain, the water, rushing up into the pipe E andagainst the elbow-neck, forces and holds the same up above the top ofthe box 0, the flange a pressing against the washer g, and it againstthe packing I, which is kept in place by the collar F. The stronger thewaterpressure the more water-tight the packing-joint, while at the sametime the pipe E is allowed to turn easily whichever way the hose iscarricd. As soon as the water is shut off, the pipe E drops back intothe cap or socket D, allowing the lid to close over the box 0.

I do not claim as new a pipe and hose coupling having a Verticalreceiving-socket and a revolving horizontally-discharging pipe operatingin said socket and forming with the same a water-tight joint, as I amaware that such couplings have been in use; but

\Vhat I claim, and desire to secure by Letters Patent, is-

1. In a street-washer, the combination,with the box C, the water supplypi'pe B, the cap or pipe-connection D, the water-tightpacking I, and thecollar F, and the mechanism for turning on the water, of the revolvingand horizontally-discharging pipe E, operating up and down in thestreet-washer cap D, and having a projecting flange, c, at its lower endto stop against the packing and prevent the pipe E from becomingdetached from the cap D, all constructed as specified,so that with thewatersupply turned on the hose-joint rises itllOX'O the top of thestreet-washer box, while with the supply turned ofi it rests in the box,substantially as described.

2. In a street-washer, the c0mbination,with the street-washer box 0, thesupply-pipe B, the cap or socket D, provided in its chamber with ashoulder, m, of the revolving pipe E. having an elbow at its upper endand a projecting flange, c, at its lower end, and rising and fallingwith the water-pressure in the socket D, the washer g, the packing I andthe collar F, substantially as described, and for the purpose specified.

3. In a street-washer, the c0mbination,with the box 0, the supply-pipeB, the cap or socket D, and the discharge-pipe E, revolving in andoperating with the water-pressure up and down in the socket D, of theflange c on the pipe E, the shoulder at in the socket D, the washer g,the packing P, and the collar F, forming means to obtain a water-tightpacking-joint between the stationary pipe or cap 1) and the revolvingand rising and falling discharge-pipe E, substantially as described andspecified.

In testimony whereof I have signed my name to this specification in thepresence oftwo subscribing witnesses.

WILLIAM STRONG.
